Overview
The Nexperia 74HC4051BQ-Q100,11 is an 8-channel analog multiplexer/demultiplexer (SP8T) qualified to AEC-Q100 Grade 1 for automotive use. It operates with a VCC supply voltage range of 2.0 V to 10.0 V and supports dual supplies up to ±5 V. The device features three digital select inputs (S0-S2), eight independent I/Os (Yn), one common I/O (Z), and an active-low enable input (E). Packaged in DHVQFN-16 (SOT763-1), it functions from -40 °C to +125 °C. Key electrical parameters include a typical ON resistance of 80 Ω at 4.5 V differential supply, propagation delay of 12 ns max at 4.5 V, and ESD protection exceeding 2000 V HBM.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards for high reliability.
- Wide analog input voltage range supporting signals from -5 V to +5 V.
- DHVQFN package design includes side-wettable flanks to facilitate automatic optical inspection of solder joints.
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel quantity or cut-tape format. Confirm that the DHVQFN-16 package variant aligns with PCB footprint constraints. Ensure the component grade meets the specific automotive application requirements defined by the system design specifications.
Selection Notes
Select this part when an 8-channel switch is needed within an automotive environment requiring extended temperature operation up to 125 °C. The HC logic family allows for flexible single or dual power supply configurations. Verify that the maximum ON resistance and leakage current limits satisfy the signal integrity requirements of the target circuit.
Part Context
This component belongs to the Nexperia 74HC/HCT4051-Q100 series of 8-channel analog switches. The 'BQ' designation specifically identifies the DHVQFN-16 package type, distinguishing it from SO-16 or TSSOP-16 variants within the same functional family.
Replacement Considerations
Direct substitutes include other 74HC4051 variants from different manufacturers such as MC74HC4051ADR2G or CD74HC4051QM96Q1. Verify pin compatibility and package dimensions before substitution.
